The inefficiency of the other EV’s could be mitigated if the charging infrastructure was in place. A real world range of 220 miles or so ...and nowhere to fast charge will plague Jaguar , Porsche , and Audi thru 2019. I have considered the Jaguar , which is also more luxurious )and hurts efficiency due to weight) than the Model X but would NOT buy them due to the current limitations!TESLA will continue having an advantage for the next few years as they have some new major advancements in battery chemistry , and the ultra-capacitors plus billions of auto-pilot miles at their advantage. What do you think?! #tesla#audi#jaguar#teslamodelx#audietron#porsche#ipace # electrifyamerica #chargepoint#teslasupercharger
